As you celebrate the first total solar eclipse visible from the U.S. mainland since February 1979, here's a look at some of the deals happening in the collective retail universe:

Best Buy

Technology haven Best Buy says it wants to help customers get the most out of this month's historic eclipse. The Minnesota-based retailer says the following items are available in every Best Buy store, as well as online:

Quiznos

If you get hungry from sun-gazing, Quiznos has you covered. All day Aug. 21, the Denver-based chain restaurant is offering customers 20 percent off orders made through the Quiznos Toasty Points app.

QVC

QVC.com will offer a curated assortment of eclipse-themed merchandise, like telescopes and sun and moon products. Further details will be released closer to Aug. 21.

Royal Caribbean

Are you the seafaring type? As the moon cruises over the sun, you’ll be able to view the spectacle from the ocean - on Royal Caribbean’s seven-night Total Eclipse Cruise.

Royal Caribbean promises “the best view” of the solar eclipse on the second day of the voyage. There will be “special celestial activities” aboard the Oasis of the Seas, including a DNCE concert with a surprise guest. Other events include enrichment lectures for adults and interactive science activities for children.

The ship leaves Sunday, Aug. 20, from Orlando, Florida’s Port Canaveral, so you can swing by the Kennedy Space Center before you head out to sea. Bookings start at $2,369 as of Aug. 7.

Royal Caribbean says seven of its other ships will offer passengers "extraordinary" partial views of the eclipse.

Southwest Airlines

Perhaps the only thing more spectacular than witnessing the total solar eclipse from the American mainland is viewing it from the sky. Southwest Airlines thinks so, too.

The Dallas-based company has identified five Aug. 21 flights “most likely to experience maximum effects” of the eclipse:

Flight 1375, Seattle to St. Louis, departing at 9:05 a.m. Pacific time

Flight 1368, Portland, Ore. to St. Louis, departing at 9:05 a.m. Pacific time

Flight 1577, Denver to St. Louis, departing at 10:20 a.m. Mountain time

Southwest says passengers on these "celestial chaser" flights will receive “commemorative ‘flare’” that includes “cosmic cocktails” and viewing glasses.

Warren Qualley, manager of meteorology for Southwest, said in a statement: “Not to throw too much shade but with 3,857 flights scheduled to operate that day using our all-Boeing 737 fleet, we'll be unmatched in offering hundreds of seats in the air over the continental U.S. that morning with a potential view of the rare sight. We plan to showcase the glow of our everyday hospitality in a different light on these celebratory flights in our summer flight schedule and our team of meteorologists is working hard to provide clear viewing of this solar spectacle from our flights! The next total solar eclipse visible in the U.S. won't occur until April 8, 2024, so don't miss this opportunity!"

United Airlines

Walmart

The largest retailer in the world invites its customers to “Get Eclipsed” this summer. Walmart has received the largest shipment in the nation of CE-certified, ISO-approved eclipse glasses from American Paper Optics and is selling them for just $1 per pair.

You also have the option of purchasing the eyewear with a factoid-filled guidebook for $3.47.

Walmart says it has millions of eclipse glasses available in thousands of stores. Ninety percent of Americans live within 10 miles of a Walmart, so chances are you’ll be able to get your hands on a pair.

“We’re definitely seeing sales heat up for certified solar viewing glasses at thousands of Walmart stores nationwide, the hottest tracking in those states along the eclipse totality path from Oregon all the way to South Carolina,” said Walmart spokeswoman Meggan Kring.

She added, “Other must-have products we expect could prove popular include sunscreen or Ozark Trail camping chairs, as well as eclipse-themed fun snacks like Luna bars, Moon pies, Sun Chips, Capri Sun or Eclipse gum to make a stellar picnic complete.”
